But the one I have doesn't depend on being sealed at the top, it sucks from near the bottom of the bottle. There is always some left in the bottom, when it won't pull any more up. I just set the empties aside as I fill & combine them later.

In any event, it's messy & not my preferred method of having fun.
That must be it. The pumper I have just plain doesn't work with Mobile-1 quarts. And yes, the tranny is a freakin' whore of a job. Its not really all that hard, just messy, uncomfortable and time consuming.....and trans fluid makes the skin on my hands feel weird after they have been soaked in it for long enough
